United Kingdom (2007–2026) against Brazil (1984–1994)
Lewis Hamilton wins this one without much argument: more titles (7 against 3) and a clearer edge in dominance once scaled against their competition, averaging 54% of the maximum possible points per season against 37% for Ayrton Senna. The picture isn't entirely one-sided though: Ayrton Senna shows a better pole rate (40.4% against 26.6%), while Lewis Hamilton keeps the edge in win rate (26.9% against 25.5%), podium rate (52.5% against 49.7%), and reliability (8.9% against 37.9% in DNFs). The two never raced for the same team, so never went head-to-head in identical machinery. The full interactive comparison (link below) remains the fairest way to bring them together despite the era gap.
